[0030] A thread-bound binding machine with a simplified support structure, such as Figures 1 to 6 As shown, it includes a supporting box frame, a drilling device 3, a threading device 4 and a control circuit. The drilling device 3 is arranged on the upper part of the supporting box frame, and the threading device 4 is arranged on the lower part of the supporting box frame. The control circuit is electrically connected to the drilling device 3 and the threading device 4 respectively, and is characterized in that: the supporting box frame includes an upper frame body and a lower box body 12, a binding platform 121 is provided on the upper part of the lower box body 12, the upper frame body is fixedly installed on the binding platform 121, the drilling device 3 is arranged on the upper frame body, the threading device 4 is arranged in the lower box body 12, and the binding platform 121 is provided with a wire groove 122 along the horizontal direction. The binding platform 121 of a traditional thread-binding machine is formed by splicing two large steel plates, and the gap between the two steel plates forms a wire groove 122. The binding switching mechanism 2 is set on one of the steel plates, and the upper support frame and the lower support frame are fixed on the upper and lower parts of the binding platform 121 respectively, so as to install the drilling device 3 and the threading device 4, and finally wrapped with an outer shell. The structure is complex, the cost is high, and the weight is large. The utility model replaces the traditional lower support frame with the lower box body 12, and there is no need to cover the lower support frame with an outer shell, which simplifies the structure and reduces the cost; the wire groove 122 is set on the lower box body 12, and the binding switching mechanism 2 is set in the lower box body 12. There is no need to set two large steel plates to splice to form the binding platform 121, which reduces the volume of the steel plate, reduces the cost, and reduces the weight.

[0031] Specifically, the lower box body 12 is provided with a binding switching mechanism 2, which includes a binding plate and a drilling slide 22. The binding plate is fixedly mounted on the upper surface of the inner cavity of the lower box body 12 and is located below the wire groove 122. A drilling slot 211 is defined on the upper portion of the binding plate, and the drilling slide 22 is slidably mounted within the drilling slot 211. The drilling slide 22 is transmission-connected to the drilling device 3. The binding plate is only required to mount the drilling slide 22 as the binding switching mechanism 2, and does not need to serve as the binding platform 121 to carry the binding material. Therefore, the binding plate is small in size, light in weight, and low in cost.

[0032] Specifically, the drilling device 3 is provided with multiple drill bits 31, and the threading device 4 is provided with multiple threading needles 41. Each threading needle 41 is located below each drill bit 31. The binding plate is provided with a lower threading groove 213 along the horizontal direction. The lower threading groove 213 is located directly below the wire placement groove 122. The lower threading groove 213 is provided with multiple threading holes spaced apart along the horizontal direction. Each threading needle 41 is located directly below each threading hole. The binding platform 121 is provided with an avoidance groove 123 corresponding to the bottom of each drill bit 31, and each avoidance groove 123 is located on the wire placement groove 122. By opening an avoidance groove 123 on the binding platform 121 to expose the drilling slide 22 and the threading holes, a conductive film is set at the position of each drill bit 31 on the drilling slide 22, and drilling is automatically stopped when the drill bit 31 touches the conductive film; after drilling is completed, the drilling device 3 drives the drilling slide 22 to move backward, thereby exposing the threading hole, and the threading device 4 works to thread the needle. The threading needle 41 moves upward and passes through the threading hole, the avoidance groove 123 and the binding hole of the binding object in turn, and the wire rope is passed through the binding hole of the binding object. At the same time, the wire rope under the binding object passes through the lower threading groove 213 and is pressed against the lower part of the binding object. Finally, it is manually tied and the knot is completed.

[0033] Specifically, if Figure 6 As shown, the binding plate includes a first plate 21 and a second strip 23. The first plate 21 and the second strip 23 are spaced apart to form a lower threading groove 213. The first plate 21 is located behind the threading groove 122, and the second strip 23 is located in front of the threading groove 122.

The first plate 21 is made of steel plate, and the second strip 23 is made of steel strip. The lower threading groove 213 is formed by the spacing between the first plate 21 and the second strip 23. No additional processing of the lower threading groove 213 is required, which simplifies the production process and improves production efficiency. The first plate 21 and the second strip 23 are respectively used to reinforce the notch of the threading groove 122 to prevent bending, thereby improving reliability and stability.

[0034] Specifically, side wire grooves 125 are respectively provided on the left and right sides of the lower box body 12.

An extension support plate 13 is provided on the front side of the lower box body 12, and the upper end surface of the extension support plate 13 is aligned with the binding platform 121. The two side wire grooves 125 guide and fix the two ends of the wire rope to the threading needle 41, so that the threading needle 41 can hook the wire rope and improve the success rate of threading. The area of ​​the binding platform 121 is expanded by providing the extension support plate 13, which increases the bearing area of ​​the binding object and adapts to binding objects of larger sizes. Figure 5 As shown, before binding, the wire rope is placed in the wire groove 122, and the two ends of the wire rope are inserted into the two side wire grooves 125 until the wire rope falls into the groove of the threading needle 41. When drilling, the drilling slide 22 moves toward the second slat 23 and passes through the wire groove 122, thereby blocking the wire groove 122 and the threading hole. After drilling is completed, the drilling slide 22 moves in the opposite direction to move out of the wire groove 122 and the threading hole, thereby ensuring that the threading needle 41 can thread the wire.

The mounting base 15 is fixedly mounted on the lower box body 12 by screws. When performing maintenance, the threading device 4 can be taken out by only removing the mounting base 15, which is convenient for production and maintenance.

[0037] Specifically, the upper frame includes a top plate 112, a mounting plate 113, and two side plates 114. The two side plates 114 are bent and formed on the left and right sides of the top plate 112, respectively.

The drilling drive mechanism includes a drilling motor and multiple transmission gears. The drilling motor drives the multiple transmission gears to drive each drill bit 31 to rotate. When drilling, the lifting drive motor 341 drives the sector teeth to rotate after being decelerated by the lifting reduction gear group. The sector teeth drive the lifting rack to move downward, thereby causing the drilling slide 32 to move downward for drilling; after drilling is completed, the lifting drive motor 341 reverses and drives the sector teeth to rotate in the opposite direction, driving the drilling slide 32 to move upward, the sector teeth tighten the connecting rope and pull the connecting rope downward, and the connecting rope pulls the drilling slide 22 backward, thereby avoiding the threading hole. After threading is completed, the drilling slide 22 resets forward under the action of the reset spring; the mounting plate 113 not only plays a supporting role, but also facilitates the installation of the lifting drive mechanism 34.
